 note = {In Japan, there are mainly two methods of Radio Meteor Observation. FM-band andHam-band Radio Observation (FRO and HRO). In 2001, so many Leonid meteor echoes appearedwith both methods that it became impossible for one echo to be separated from the others inHRO method because of saturation effects, though these echoes in FRO could be separated. Thelower frequency of the HRO radio waves caused this saturation. This research is to estimate thenumber of HRO echoes during the saturation period around the Leonid peak by comparing HROwith FRO. In this paper, to estimate the number of the echoes at the peak time, a useful newindex named "FROIHRO ratio" is deflned, which shows the ratio of the echo numbers in FRO toHRO. As the result, the number of HRO echoes at the Leonids' peak time in 2001 was successfullyestimated, and its profile during saturation in HRO became clear. Additional analysis for the 2001Geminids in the same way, and its comparison with that of Leonids, make it possible to find somerelative characteristics of these meteor showers such a~s the geocentric velocity, the beginning andend heights of the meteors, and so on.Consequently, the FROIHRO ratio can make the saturated data usable and also reveal some otheraspects of meteor showers., 資料番号: SA4641775000},
